  This heatsink fixing device has a fixed height between the pedestal and the backboard, and can only be used for one or two kinds of standard circuit boards. did. Even if it is a well-designed standard, if an error occurs in production, when the radiator is installed, it cannot be firmly fixed, and the heat radiation effect may be greatly reduced.

  An object of the present invention is to provide a radiator fixing device that is easy to assemble, is securely fixed, can be used for various circuit boards having different thicknesses, and can reduce the cost of manufacturing various molds.

  In order to achieve the above object, the present invention provides a radiator fixing device. The radiator fixing device of the present invention fits and fixes a radiator to a circuit board and makes it contact an electronic device that generates heat. The radiator fixing device of the present invention includes a backboard and a frame. The backboard has at least one convex column, the convex column has a tip portion that penetrates the circuit board and is fitted with an elastic body, and has a fitting portion near the tip portion. The frame has at least one column in a portion corresponding to the convex column, and each column has a first protrusion. The first protrusion has a perforation for accommodating the convex column and a slot for accommodating the fitting portion. The groove hole extends and leads to perforation, and the extended groove moves the fitting portion. The frame is fixed to the convex column by moving in the horizontal direction, the vertical direction, or swinging.

  The radiator fixing device of the present invention is a combination of a frame, a backboard, and a convex column, so that the radiator can be firmly fixed and can be used on various circuit boards with different thicknesses. There is no need to do so, and it has become possible to curb unnecessary expenditures.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a radiator fixing device according to an embodiment of the present invention. As shown in FIG. 1, the radiator fixing device of the present invention includes a frame 10, a radiator 40, a circuit board 60, and a back board 20. The circuit board 60 has a perforation 61 and an electronic device 50. The frame 10 is used to fix the heat radiator 40 to the circuit board 60 in combination with the back board 20. Further, the radiator 40 is in close contact with the electronic device 50 for heat dissipation. The shape of the radiator 40 is not limited to the shape shown in the figure. As shown in FIG. 3, it may be cylindrical, or may be a polygonal or geometric pillar (not shown). FIG. 3 is a perspective view showing a radiator and a frame according to another embodiment of the present invention. As shown in FIG. 3, the shape of the frame 10 is a quadrangular, circular, or polygonal shape depending on the shape of the radiator 40 because the radiator 40 is fitted into the frame.

  The backboard 20 has a plate body 21. The plate body 21 has convex pillars 22 projecting upwards at the four corners. Each of the convex columns 22 has a tip portion, and has a fitting portion 221 in the vicinity of the tip portion. As for the convex pillar 22, when the front-end | tip part penetrates the circuit board 60 to which each respond | corresponds, the elastic body 23 (a spring is preferable) will be engage | inserted. The diameter of the fitting portion 221 is smaller than that of the convex column 22, and the number of perforations 61 of the circuit board 60 corresponds to the number of convex columns.

  The frame 10 is a frame body having an opening at the center, and one surface of the radiator 40 is fitted into the frame. There is at least one column 11 in a portion corresponding to the convex column 22 of the frame 10. The support column 11 has a first protrusion 12a and a second protrusion 12b that protrude outwardly perpendicular to the support column 11, respectively, at corresponding positions slightly below the upper end and the upper end. The first protrusion 12 a has a perforation 121 and a slot 122. The perforation 121 passes through the convex column 22. The slot 122 accommodates the fitting portion 221 and extends to communicate with the perforation 121. As shown in FIG. 1, the grooves extending from the slot 122 are all in the same direction in the horizontal direction or the vertical direction of the frame 10. The second protrusion 12 b has a second perforation 123. The groove extending from the second perforation 123 corresponds to the perforation 121 and the slot 122 extending from the second perforation 121 and connected to the perforation 121. The second perforation 123 accommodates the convex column 22. As described above, when the radiator 40 is fitted into the frame 10, the convex column 22 passes through the second perforation 123 of the second projection 12b and the perforation 121 of the first projection 12a. When the second protrusion 12 b compresses the elastic body 23 by applying pressure to the elastic body 23, the slot 122 of the first protrusion 12 a corresponds to the fitting portion 221 of the convex column 22, and naturally the slot 122. , The fitting portion 221 moves to the opposite side of the perforation 121. That is, it moves in the horizontal direction of the frame 10 (when the groove is in the vertical direction, it moves in the vertical direction of the frame 10). When the fitting portion 221 is positioned in the slot 122 and the elastic body 23 applies pressure to the circuit board 60 and the second protrusion 12b by elastic force, the fitting portion 221 is fixed in the slot 122. The frame 10 is firmly fixed on the circuit board 60.

  FIG. 4 is a plan view showing a slot according to another embodiment of the present invention. As shown in FIG. 4, the only difference is the groove in which the slot 322 extends. The slot 322 of the first protrusion 12 a is extended along the tangent direction so as to go in the plane of the frame 10 on the opposite side of the perforation 121 and is connected to the perforation 121. The extending groove is arc-shaped and gradually becomes narrower as it goes ahead, and a fitting portion 221 is arranged at the end that becomes thinner. Although not shown in the drawing, the second perforation 123 of the second protrusion 12 b corresponds to the perforation 121 and the slot 322, and the frame 10 rotates along the groove extending in the tangent direction of the frame 10. And is fitted onto the convex column 22 and fixed on the circuit board 60.

  FIG. 5 is a perspective view showing a radiator fixing device according to another embodiment of the present invention. As shown in FIG. 5, the convex pillars 22 may be arranged directly on the circuit board 60. The frame 10 is fixed by moving the convex column 22 in the horizontal direction, the vertical direction, or rotating.

  Although the present invention discloses preferred embodiments as described above, these are not intended to limit the present invention in any way, and anyone skilled in the art is within the spirit and scope of the present invention. Various changes and modifications can be made. Therefore, the scope of protection of the present invention is based on the contents specified in the claims of the utility model.
